Precision Castings & Machined Components for Pumps & Valves

Precision Pump & Valve Components: High-Performance Casting & Machining

Components for fluid control systems demand exceptional durability, dimensional accuracy, and superior resistance to extreme pressure and corrosive media. Vast specializes in high-precision investment casting and multi-axis CNC machining for the pump and valve industry, delivering critical parts that ensure operational reliability in the world’s most demanding environments.

From high-speed impellers to heavy-duty valve housings, we provide “drawing-to-part” solutions that meet the stringent requirements of global OEMs.

Core Pump & Valve Component Portfolio

We manufacture a wide array of “near-net-shape” castings and fully finished parts engineered for zero-leakage performance:

• Impellers & Diffusers: Precision-cast using the lost wax method for optimal hydraulic efficiency, dynamic balance, and reduced cavitation.

• Valve Bodies & Bonnets: High-pressure resistant housings designed for gate, globe, ball, and check valves.

• Discs, Wedges & Plugs: Precision-machined, wear-resistant components for reliable metal-to-metal sealing.

• Pump Casings & Volutes: Robust, corrosion-resistant structures designed for high-flow industrial environments.

• Stems & Shafts: High-tensile strength components machined to micrometer tolerances for smooth actuation and long-term sealing integrity.

Materials Engineered for Severe Service & Extreme Conditions

To combat mechanical wear and chemical erosion, we utilize a diverse range of high-performance alloys (covering sizes up to 500mm and weights up to 80kg):

• Stainless Steel (304, 316, 316L, 17-4PH): The industry standard for general corrosion resistance and sanitary applications.

• Duplex & Super Duplex Steel (CD4MCu, 2205, 2507): Engineered for high-chloride, desalination, and marine environments.

• Nickel-Based Alloys (Inconel, Hastelloy): For aggressive chemical processing and high-temperature services.

• Carbon Steel & Low Alloy Steel (WCB, LCC, WC6): High-strength solutions for industrial power generation and oilfield infrastructure.

The Vast Advantage: Reliability in Flow Control

As a premier pump and valve casting manufacturer in China, partnering with Vast ensures:
